In the hospital, police said a man rode his bike up to the emergency room, went inside and took the elevator to the third floor. A surveillance camera showed a man police identify as David Owens, 29, entering Room 320. An arrest report released Monday said a hospital employee heard a bang. Then, “...she looked in the room and saw the defendant shoot one of the victims. She ran and hid,” the report said.

"I've done something wrong," Owens said after the shooting, according to a police report.

“This is, possibly in my 29 years of doing this job, the most unusual homicide I’ve ever had to deal with,” Prosecutor Gary Beatty said.

Dead in her bed was Cynthia Zingsheim, 92. Family members said she was a devout Christian and a former Wisconsin resort owner who moved to Titusville to be with her sister. Next to her was Carrie Rouzer, 36.

“She would have done anything to help anybody without a batted eye. She wouldn’t have hurt a fly,” said Rouzer’s son, Casey Smith.

Owens’ presence at an arraignment hearing was waived Monday. His attorney entered a not guilty plea. Owens has displayed mental health problems in the past and was found mentally incompetent to stand trial in a misdemeanor case earlier this year, Beatty said.
